左心室射血分数预测中老年心力衰竭患者新发缺血性脑卒中的临床意义

Clinical Significance of Left Ventricular Ejection Fraction in Predicting New Ischemic Stroke in Middle-Aged and Elderly Patients with Heart Failure

探讨左心室射血分数(LVEF)预测中老年心力衰竭(HF)患者新发缺血性脑卒中(CVA)的临床意义。方法为:回顾性分析中老年HF患者126例,根据随访诊断分为CVA组16例和非CVA组110例,运用Logistic回归分析老年HF患者发生CVA的相关因素。结果:CVA组左心房内径、左心房容积及LVEF明显高于非CVA组,差异有统计学意义(P<0.05)。Logistic回归分析显示,左心房内径、左心房容积及LVEF是中老年HF患者新发CVA的独立预测因素。结论:中老年HF患者中,LVEF与新发CVA独立相关,LVEF可能是一种老年心力衰竭患者新发CVA的独立预测因素。

To investigate the clinical significance of left ventricular ejection fraction(LVEF)in predicting new ischemic stroke(CVA)in middle-aged and elderly patients with heart failure(HF).Methods:126 middle-aged and elderly patients with HF were analyzed retrospectively.According to the follow-up diagnosis,they were divided into CVA group(n=16)and non CVA group(n=110).Results:The left atrial diameter,left atrial volume and LVEF in CVA group were significantly higher than those in non CVA group(P<0.05).Logistic regression analysis showed that left atrial diameter,left atrial volume and LVEF were independent predictors of new CVA in middle-aged and elderly patients with HF.Conclusion:LVEF is independently associated with new CVA in middle-aged and elderly HF patients,and LVEF may be an independent predictor of new CVA in elderly HF patients.
